perf report: Introduce --inline option
It takes some time to look for inline stack for callgraph addresses. So it provides new option "--inline" to let user decide if enable this feature. --inline: If a callgraph address belongs to an inlined function, the inline stack will be printed. Each entry is the inline function name or file/line.
